Engorged

J💜

Hey mama's. My little guy is almost a week old. I started off breast feeding and my milk is in and great, but we were having some other issues and decided to supplement with formula a bit. Anyways now he only wants a bottle and I'm super engorged now and he won't take the boob at all. How do I make sure I don't get mastitis and how do I start to dry up thru the pain? Any tips or advice??
